RT Journal Article T1 A P2P Scheme for Debating and Voting with Unconditional Flexibility A1 López García, Diego Antonio A1 Pérez Torreglosa, Juan A1 Vera, David A1 Sánchez Raya, Manuel AB Most e-voting schemes make use of central servers. Users are obliged to trust these servers,which represent a vulnerability of the scheme. In the last few years, a very small group of schemeshas been published that overcomes this handicap by using a peer-to-peer (P2P) approach. Theseare known as boardroom e-voting schemes, whereby users take the role of the servers. They actas managers of the process: they cast votes, keep a record of them, and verify the cryptographicoperations made by others. Nevertheless, ballots must fulfill certain constraints which conflict withthe possibilities of recent debate tools. These tools allow users to decide what to vote on, thus enablingthe ballot frame to remain unknown before the voting process. The scheme presented here is a newboardroom voting protocol. It provides privacy, eligibility, and verifiability among other relevantfeatures. The key advantage of this system is its high degree of flexibility, due to the absence of aneed to impose any constraint on the ballots. This paper includes experimental results with twodebate groups.
